Macro partitioning
High intake of saturated fatty acids (SFA) from modern domesticated animal products and dairy increases LDL cholesterol and cardiovascular disease risk compared to ancestral diets rich in unsaturated fatty acids.
Prioritize unsaturated fatty acids (especially omega-3s) and fiber-rich foods over high-fat dairy and fatty cuts of domesticated meat. This shift aligns your diet with evolutionary norms and helps lower LDL cholesterol, reducing cardiovascular risk.
GoodSupportsHIGH confidence
A higher intake of high-fat dairy and meat products produces a divergent fatty acid profile that can increase the risk of cardiovascular and inflammatory disease... The effect of saturated fat on cardiovascular events is commonly attributed to LDL-C increases followed by accumulation in atherosclerotic plaque... Contemporary Americans have total cholesterol (TC) and LDL-C levels greatly exceeding those of HGs and other free-living primates
Why this rating
The paper cites multiple systematic reviews, RCTs, and cross-population observational data, though it acknowledges confounding variables in observational studies.
